Product Code: KH20x6.4 KRSD
|
| Main Features: |
· Shuttle Shot Function
Shuttle Shot is a Canon Exclusive Technology that enhances production capabilities. At the touch of a button, this feature
allows the operator to zoom back and forth instantly between any two positions. It can be used to zoom to the telephoto position to check focus and then return instantly to the original position or
you can “shuttle” between any two zoom positions at any time.
·
Compact Design
The KH20x is smaller in size and lighter in weight compared to the traditional BCTV lenses, which allows ease of use when carried on a
shoulder.
·
Newly Developed Advanced Drive Unit
Various companies have rolled out cameras with lens aberration correction functions in recent years. For this reason, the KH20x6.4
KRSD SY14 is fitted with a camera-communication interface to support these separate aberration correction functions.*1
The KH20x6.4 KRSD SY14's zoom can travel end to end in 1.0 seconds. On the newly developed advanced drive unit, the Memo switch, which sets specific zoom positions for the Shuttle Shot function (see
right page), has been changed to a push switch. On previous drive units, to memorize the zoom position, the operator had to adjust its position by a volume switch. The memo switch enables more
reliable Shuttle Shot setup in the fi eld where more consistent functioning of the controls is required.
*1. Check with the camera manufacturer to see whether the KH20x6.4 KRSD SY14 is compatible with the camera's aberration correction functions.
